Don’t see the benefit?
Many people like me, have a video topics. When a member is watching something online and he wants to post a message, he can’t! because the connection with the video will be lost after the refresh. Why did you think youtube added ajex?!
Please add this future as a built-in option with an option to turn this off/on via acp.

In busy boards like I have, it’s very important to save traffic and resources. Emoticons can take a lot of resource and traffic too, so what I did is- uploaded my emoticons to 3 different free hosts severs, and made a mod that give me the option to put a different link in every emoticon in ACP emoticons manager. So in case one server bans me or if I see its too slow, I can simply upload to another host and change the links in ACP. In 2.3 the only option you have is to change the whole path of images… I think it will be great built in feature to have in ipb3.

What's so great about AJAX quick reply? Nothing, absolutely nothing other than being able to say "OOH! LOOK, IT HAS AJAX, HOW COOL!", it usually breaks browsers' back functions and is FAR more annoying than useful.

Just an over hyped and useless feature that's not needed, has never been needed, and never will be needed...

If someone watche a movie at my board and want to post a comment, he can't without refreshing the page! In the mod I have right now, every user can disable Ajex in the quick replay.

Another great privet mod I have right now, but I sure it will be useful for a lot of people, especially for busy boards… Hotlinking emoticons In busy boards like I have, it’s very important to save traffic and resources.
